CHURN.

SPECIFICATION forming part of Letters Patent No. 425,706, dated April15, 1890.

Application filed June 29, 1889. Serial No. 316,009. (No model.)

To all whom, it nuty concern.-

Be it known that I,W1LLrAM-S. SNYDER,.a citizen of the United States,residing at WVapakoneta, in the county of Auglaize and State of Ohio,have invented new and useful Improvements in Ohurns, of which thefollowing is a specification.

My invention relates to barrel-churns; and the purpose thereof is toprovide simple and improved means for securing the cover of the churn toits body in such manner as to form a tight joint between the parts, theclamping devices being capable of locking and releasing the cover by asingle instantaneous movement.

The invention consists in the novel features of construction andcombinations of parts hereinafter described and claimed.

To enable those skilled in the art to make and use said invention, Iwill now describe the same in detail, reference being had to theaccompanying drawings, in which Figure 1 is a plan view of a churn inwhich my invention is embodied. Fig. 2 is a vertical section of thechurn head or top in the line 00 00, Fig. 1. Fig. 3 is a detail view ofthe central clamping-ring. Fig. 4 is a detail sectional elevationshowing one of the journalsupports of one of the locking-yokes. Fig. 5is a detail view showing the action of the locking mechanism.

In the drawings, the reference-numeral 1 denotes the body of thechurn,which may be fastened at top and bottom by hoops 2, having theirends connected by clamping-screws 3, by which the'hoops may betightened.

Upon the upper end of the churn is mounted a cast-metal lid-rin g 4,having a flange 5, which enters a kerf in the staves. posed of castmetal, and is provided upon its upper surface with a raised rib 6,formed near the opening, by which access is obtained to the churn. Thelid or cover consists of a wooden disk 7, having a metal ring or binding8, secured to its upper surface by screws, and having a flange inclosingthe periphery of the wooden cover, which is provided at its edge with acircumferential channel receiv- This ring is coming a packing-ring 9,lying. in said channel and partly inclosed by the flange of the metalrin 8.

P rojecting from the periphery of the ring 8 are lugs 12, separated fromeach other by substantially equal intervals. Rising from the lid-ring 4at similar intervals are brackets 13, which receive journals or pivots14 upon the ends of yoke-shaped bars 15, provided at or about theirmiddle portions with curved plates 1.6,which rest,when the yokes areturned down, upon the lid-ring upon the edges of the staves, whichproject above the said ring, as shown. Upon the ends of each yoke,substantially in line with the pivotal axis thereof, are mountedadjustable cam-lugs 17, which may be formed of screw-threaded boltstapped into the ends of the yokes.

In use-the cover is fastened and hermetically sealed by laying it uponthe lid-ring, with the packing-ring 9 upon the raised seatrib 6. Theyokes are then raised and the cover is turned until the lugs 12 arebrought opposite the brackets 13, whereupon the yokes are turned downuntil the curved plate 16 rests upon the chine. This movement brings thecam-lugs 17 down againt the lugs 12, forcing the packing-ring 9 downtightly upon its seat, while the cam-lugs 13 are turned just far enoughso that the upward strain of the cover tends to hold the yokes downinstead of throwing them up and releasing the cover.

Upon the body of the churn is mounted a central hoop or ring 18, clampedthereon by means of bolts 3, similar to those used on the end hoops.Upon one of the half-sections of this clamping-ring 18 are formedjournals 19, one of which has a squared end 20, to enable the operatorto mount the churn in journalsupports and attach a crank in the usualmanner.

That I claim is- 1. In a churn, the combination, with a lidring lyingwithin the staves and having a raised rib or seat, of a cover having apacking-ring lying on the seat and provided with lugs projecting fromits periphery, and yokes having journals at their ends lying inbracket-supports on the 1id-ring, and provided with adjustable cam-lugsbearing upon the lugs of the cover, substantially as described.

2. In a churn, the combination, with a lidring 4:, having a raised ribor seat 6, of a cover 7, having a packing-ring 9 and provided with lugs12, yokes 15, journalcd at their ends in brackets 13 on the lid-rin gand provided with adjustable cam-lugs 17, mounted on the ends 10 of theyokes and substantially in line with the axis thereof, said yokes beingprovided with curved plates 16, mounted on their middle portions,substantially as described.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
